However, antibiotics and especially β-lactam can be found as residues in different animal products particularly in milk from treated cows. The present survey was conducted between July 2016 and June 2017 in four governorates from Northern Tunisia, namely Jendouba, Béja, Kef and Siliana. A total of 10.699 bulk cow's milk samples were collected and tested for the presence of β-lactam residues using the Penzym® test. Among them, 14 were positive. Even if the contamination rate was low (0.13%), the quantity of refused milk due to presence of β-lactam residues was relatively high (102.10 3 L) which represents 2.6% of the total volume of refused milk (3.874.10 3 L). Milk samples collected from the Kef governorate showed the highest proportion of antibiotic residues (0.64%), followed by the governorate of Béja (0.13%) and the governorate of Jendouba (0.07%).The presence of β-lactam residues in milk represents a real threat to animal and human health, systematic monitoring could be implemented in Tunisia for all milk productions in order to reduce these risks.

Blended pastes of partially replaced ordinary Portland cement with different metakaolin amounts 5%, 10% and 15% were prepared, then they were hydrated with water for various time intervals of 1, 3, 7, 14 and 28 days. At each time interval, the hydrated paste specimens were tested for compressive strength, hydration kinetics and followed up using differential scanning calorimetry, X-ray diffractometry analyses and scanning electron microscopy techniques. Results showed that the blended pastes OPC-MK10 recorded the highest compressive strength values at all the hydration times reaching 33.10, 86.40, 101.20, 112, and 122 MPa with increasing the age of hydration as compared with the neat samples which recorded 31.70, 65.20, 72.6, 82 and 101.30 MPa respectively. Meanwhile, the OPC-MK10 blend showed a decrease in the free CaO content reaching 4.07%, 4.27%, 4.23%, 4.19%, and 4.11% CaO with increasing age of hydration compared with the neat samples which recorded 4.27%, 5.15%, 5.42%, 5.61%, and 5.96% CaO respectively. The DSC thermograms results for the hardened neat and OPC-Mk10 pastes at the 14 and 28 hydration days showed the formation of hydrated materials mainly calcium silicate hydrates, calcium sulphoaluminate hydrates and calcium aluminates hydrates. The X-ray diffractometry analyses of both hardened neat and OPC-MK10 showed that, the intensity of calcium hydroxide peaks of OPC-MK10 was lower than in case of neat OPC, while the peak of the hydration products

This association is poorly understood, and no intervention is proven to slow cognitive decline. There is evidence that cooler dialysis fluid (dialysate) may slow white matter changes in the brain, but no study has investigated the effect of cooler dialysate on cognition. This study addresses whether cooler dialysate can prevent the decline in cognition and improve quality of life (QOL) in HD patients.Methods: This is a multi-site prospective randomised, double-blinded feasibility trial. Setting: Four HD units in the United Kingdom.: Participants and interventions Ninety HD patients randomised (1:1) to standard care (dialysate temperature 36.5C) or intervention (dialysate temperature 35°C) for 12 months. Primary outcome measure: Change in cognition using the Montreal Cognitive Assessment (MoCA). Secondary outcome measures: Recruitment and attrition ...

The results showed that the initial and final setting times of the hardened blended pastes were reduced significantly by increasing the amount of the added alumina. In addition, the compressive strength and the hydraulic property measures of the hardened blends showed progressive improvement reaching approximately 42% and 23% after the early ages of hydration (1 and 3 days), respectively. According to such conditions, these cement blends could be applied in many concrete applications, such as high speed construction, rapid repair, frost prevention, tunneling, shoring, gas and oil well cementing, that require concrete to have rapid setting and strength development abilities.The improvement of the physico-mechanical characteristics and the hydration kinetics of the hardened blended pastes with the recycled alumina were explained after the microstructure study included the e...

A total of 71 pesticide analyses have been submitted to the Pharmacy and Toxicology Laboratory of the School of Veterinary Medicine of Sidi Thabet in Tunisia. All the cases were first referred either through the clinical and/or pathological departments of the Veterinary School, the private and/or governmental veterinarians or directly by the pet owners. Among the total number of the suspected samples, 21 (29.6%) cases were found positive for various kinds of pesticides. Carbamate insecticides were the most frequently implicated pesticide (52.4% of the total positive cases), followed by organophosphate insecticides (19%), then rodenticides-anticoagulants and rodenticides non-anticoagulants (14.3% each). Therefore, carbamates and organophosphates are the most implicated group of pesticides in intoxications (71.4%). Among the 21 positive cases were 11 dogs, 4 cats, 3 poultry, 2 ruminants, and 1 case of bee poisoning. Partition chromatography (HPLC) has been used to characterize the incriminated pesticides. The aim of this survey was to determine incidence and characteristics of pesticide poisoning in domestic and farm animals in Tunisia. The reported results are useful for epidemiological cartography and medical management of intoxicated animals.

The BSC is one of the most widely used approaches making new in roads into the academic and business literature. Therefore, the present paper reports the findings of a postal questionnaire survey undertaken in 2010 that examines the extent of the adoption rate of BSC and to which degree potential explanatory factors influence the adoption of BSC in KSA firms. In addition, the effect of BSC on performance-has opened up flood gets of new research. In addition BSC, which has an effect on firms performance-assigns a new role model to global planners and economic strategist in order to accommodate all those issues, problems and obstacles emanating from the growing colossal form and size of enterprise. It is a comprehensive study how the balanced score card system, has become an unavoidable necessity in order to see the far-reaching effects and after effects of the applicability of BSC on firm performance. Hence adoption of BSC acts as an innovator; it is a new variable applied on firm performance-is a post structuralist stands points in the area of prising, budgeting and accounting. It basically seeks for creating equilibrium between adoption and firm performance. Results demonstrate that there is indeed a significant relation between BSC and some potential explanatory factors giving direction for further research. In addition BSC system which makes a tremendous impact on firm's performance-assign a new role modern to the global planners and big strategist in ordered to accommodate an address all those issues and crises emanating from growing colossal form, nature and shape of enterprise. Adoption of BSC system and its impact on firm performance is an analytical and objective study made to involve a system through which the Managerial apparatus can be more effective in running companies organisational processes. The present study comprehensively shows how the balanced score card system has become an unavoidable necessity in order to see the far-reaching effects and after effects of the applicability of BSC on firms' performance. Hence adoption of BSC acts as a new innovator; it is a new variable applied on firm-performance-is principally a post structuralist perspective operative in manifold areas viz, pricing, budgeting and accounting etc. It basically seeks for and equilibrium between adoption and firm performance. Hence it would be in fitness of things to argue that the BSC system a sign a new role model to the planners and strategist all over the world; it acts as a new modus operandi to address the new incoming challenges in the areas of pricing accounting and budgeting. BSC thus gives new teeth to the planner's business analysts and strategist and above all to the managerial apparatus. Hence from the post structurlist stand points it would be in fitness of tings to apply BSC as a new modus operandi; a new motivator to facilitate manifold organisational activities. Hence BSC system in the present global scenario can act as a new variable to establish a balance between adoption and performance.

Study level/applicability Graduate and upper undergraduate classes. Case overview This case deals with an information technology (IT) outsourcing company based in Egypt which has ventured into the international market right from the start without establishing itself first in the local market. Its record of success was due largely to a group of young Egyptian entrepreneurs with an international orientation. Their strongly held values were translated into an organizational culture that was manifested in the company's relationships with its clients, whether multinational companies or regional governments. This mutual trust has generated work through referrals and has saved the company the need, at least initially, to adopt a proactive marketing strategy. In addition to culture the company's structure has shown considerable agility in dealing with the unexpected demands from clients through developing strong functional departments ...

Gas reservoirs in the Nile Delta of Egypt are characterized vertically by its thin beds of sands ... more Gas reservoirs in the Nile Delta of Egypt are characterized vertically by its thin beds of sands and shale and laterally by severe variations in facies. These challenges in the static modeling have a strong impact in the dynamic modeling which can be summarized in the following points. First, the vertical sequence of sands and shale leads to the difficulty in detecting a single gas-water contact in the field. Second, the vertical heterogeneity leads to the use of fine gridding especially in the vertical direction to accurately simulate the fluid flow in the reservoir. Third, the lateral variation in facies forces to use different saturation functions at different parts of the reservoir.The dynamic behavior of pressure and production performance from few wells (total seven wells) producing from this field show severe vertical discrepancy in pressure, gas and water production. This adds another challenge in the dynamic modeling and leads to dividing the field into three main reservoir...

The fact that this regulatory role is fragmented has motivated businessmen to focus their energies on managing their links with the bureaucracy in order to obtain resources for their firms or to secure markets for their products and services. In some cases, this external orientation has distracted businessmen from improving the efficiency or developing the internal capabilities of their firms. This is detrimental to the long-term viability of these firms, particularly in the face of the declining role of the bureaucracy in the economy. This article attempts to outline the main features of the business environment in Egypt with a particular focus on the role of the bureaucracy. Different forms of strategies adopted by business firms will be presented. Finally, implications for the efficiency of business firms will be discussed. The Egyptian economy, like that of other developing nations, can be classified as an imperfect economy. Resources are limited and have low mobility; entry into different industries is impaired by high capital requirements, credit restriction, limited information and complicated administrative procedures. Since the early 1970s Egypt has been undergoing a process of liberalization, aiming at increasing the share of the private sector in the economy. This has intensified in recent years owing to the constant pressure by international agencies asked to reschedule Egypt's foreign debt. 1 The government is also attempting to rationalize state-owned enterprises (SOEs). While the government is encouraging the private sector through a variety of incentives, it still plays a major role in allocating the limited resources of the country. Raw materials and semi-finshed products which are available locally have been under considerable public control. Fixing prices, quotas and permits have been used to allocate these resources among competing firms. Of course, SOEs have higher priority over private business firms (PBFs) in this respect. Some resources, such as cotton yarn and aluminium sheets, are totally controlled by SOEs. 2 Imports, because they utilize scarce foreign exchange, have been

The programme aims at improving the performance of state‐owned enterprises for the purpose of improving their saleability. Long‐term objectives include improving efficiency and export potential of Egyptian industry. The programme covers the areas of finance, physical assets and the management systems of companies. Contends that effects of the programme are still inhibited by the inefficiency of the Egyptian bureaucracy.

Egypt, for one, still has about 70 percent of total national investment under the control of State‐owned enterprises (SOEs); quite an improvement over the sixties and early seventies when this ratio was 90 percent (Handussa, 1989). Judging by the rate of change since the declaration of the open‐door policy in 1974, it is wise to assume that SOEs will continue to play a dominant role in the Egyptian economy for the foreseeable future.
